How to work it out

  1. Turn the percentage into a decimal: 21 ÷ 100 = 0.21
  2. Multiply: 0.21 × 48 = 10.08
  3. Check: Work backwards: 10.08 ÷ 48 × 100 = 21%.

Another method. As a proportion of part to whole: 21/100 = part/48, so part = 21 × 48 ÷ 100 = 10.08. Both methods always give the same answer.

In a spreadsheet: =21%*48. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

What the result means

10.08 is the 21% share of 48. The remaining 79% is 37.92, and the two parts add back up to 48.

Discounts: 21% off an item priced $48 saves $10.08, so you pay $37.92.

Adding and taking away 21%

Increasing 48 by 21% gives 58.08 and decreasing it by 21% gives 37.92. These do not cancel out: raising 48 by 21% and then lowering the result by 21% ends at 45.8832, because the second 21% is taken of a bigger number.
